My invention relates to improvements in portable electric lamps, and has forone of its objects to provide a new form of insulated lamp holding device including-an improved lamp guard. i

Anotherobject is to provide animproved portablelamp having a minimum 'number of parts and in which the guard may be easily be understoodthat the specific construction and form herein shown is to be taken as illustrative and not in a llmited sense.

In the accompanying drawings, like portions of the device are designated by like .1

characters thruout the several figures.

Fig. 1 is a side elevation partially in. sec-' tion.

Fig. 2 is a transverse sectional'view'taken on a line corresponding to line 22 of Fig. 1.

Fig. 3 is a perspective View of a portion of the guard rings and illustrates the method 2 of securing the guard in position.

of Fig. 1.

Referring now to the drawings, thehandle 1 is preferably made of flexible and resihent material such as rubber, and is provided with an enlarged portion 2 having a recess or chamber 3 therein to receive the socket 4. Suitable conductors 5 extend thru the handle and are secured to the socket.

The lamp 6 is protected by the guard 7 which is made of insulating materlal, preferably fibre, and consists of a plurality of comparatively thin strips 8 which are connected at their upper ends, as shown in Fig. 1, to the ring 9. The upper portions of the ribs or strips 8 are curved to conform somewhat to the contour of the bulb used and are provided with L shaped hooks 10 which are in serted thru the radial openings in the ring 9, the ring is preferably made of fibretubing.

The strips 8 are held in spaced relation by means of the split rings 12 and '13. The split ring 12 comprises four semicircular insulating members 1l'15 -16 and 17' preferably fibre, the members 14 and 15 being secured together by means of eyelets 18 to form one half of the split ring, and themembers 16 and 17 also secured together by similar eye- 1 so positioned that when securedtogether overlapping ends 19 are provided, as shown in Fig. 3, and which may besecured together by means of the bolts 20.- y y Y The upper members 15 and 17' are provided with the radial slots 21,and the lower members 141 and 16 with corresponding radial slots 22. It will be noted that as the slots in the members 14 and 16, and 15 and 17 extend in opposite directions respectively, when the strips 8 areinserted in these slots and the" eyelets18 secured in place, all of the strips in each half of the guard are held securely in spaced relation. The strips 8 are provided with notches 23 and 24 to engage thering members and prevent longitudinal movement.

Thesplit ring 13 issomewhat smaller. in

1 lets to form the otherhalf; The members are diameter but is otherwiseexactly the same constructionas the ring12. The strips 8 are provided with notches 2'5 and 26 to engage L the semicircular members 27 and 28 respec- Fig. 4 is a sectional View taken on line 44 tively. i i i 1 After the guard is assembled as described it may be secured to the enlar ed end 2 of the handle 1 as shown in Fig. 1 y y springing thelower ends of thetwo halves of the guard outwardly, as shown by dottedlines, andinserting' the enlarged portion of the handle in the ring 13, thetwo halves of the ring are then pressed together snugly against the'yielding material of the handle until the bolts 20 can be inserted and secured inplace; The ring 13 is slightly smaller in inside diameter than the outside diameter 0151116 handle so that considerable pressure isnecessaryto bring the parts into alignment so that thebolts 20 may be'inserted. i

The'handle is provided with an annular groove 29 in whichthe ring seats, theshouL ders of the groove assisting :to prevent longitudinal movement. y s 1 a ring.

The inner edges of the lower ends of the strips 8 are parallel with and also press snugly against the handle, the inwardly extending portion 30 seating in the groove 29. An adjustable hook 31 is secured to one of the strips 8.

It will be noted that therubber handle providesai efficient shock absorbing device and that the guard, handle and lamp are held securely in parallel relation with a minimum number of parts. The actof clam-ping the guard on the handle also clamps the socket securely.

The members 15 and 17 of the ring 12 are identical and interchangeable, as are also members '14 and 16'. The corresponding members of the ring 13 are also interchange- -i 7 aving-thus described my invention, what I claim as new and desire to secure by Letters Patent is; I U o 1 A portable electric lighting device comprising a flexible rubber handle having a chamber therein, a socket in said chamber to receive an electric lamp, a guard around'said lamp comprising radially disposed insulating strips secured. itog ether at their upper' ends, the lower ends of said; strips'beingsecured to a sectional ring each half of said ring comprising flat insulating semicircular members having oppositely extendiijigslots to receive the ends of said strips and secured for detachably securing together the halves of said arcuate members to form a circular 2. Aguardforelectric lamps comprising pl l e frc f fiat strips of nsulating. ma-

' terial disposededgewise radially around the lamp,- a means for securing the corresponding-ends, of said strips in adjacent spaced relation, a sectionalring to which the opposite ends of said strips arezat'tached, each section of said ring comprising a plurality of arcuate members having oppositely disposed radial slots therein, said sections, being secured together to form a separable split ring, said stripsint'erlocking in said slots.

;3; A combined supporting and clamping rin'g for, rubber handled hand portables coinprisii'i'gaplura'lity of sections detachably secured together, each of said sections comprising a plurality ofarcuatemembers, one of said members having outwardly extending slots, a corresponding member having in wardly extending slots, strips in said slots, said'members cooperating with said strips to hold said strips perpendicular to said ringstrips radially disposed edgewise around said lamp, means for securing the corresponding ends of said strips together, means for clamping the opposite ends of said strips in spaced relation around said handle, said means comprising cooperating arcuate members having aligned oppositely disposed slots therein to receivethe strips, the strips having locating notches to receive the arcuate members, means for securing the arcuate members together to form ring sections, and means for detachably clamping said sections snugly around said handle whereby said socket said handle and said guard are clamped resiliently in parallel relation.

5. A portableelectric lightingdevice comprising a, flexible rubber handle having a chamber therein, a socketein said chamber to receive an electric lamp,a guard around said lamp comprising radially disposed insulating strips secured together at their upper ends, the lower ends of said strips being secured to asectional ring, each section of said ring comprising flat insulatingsemicircular members having oppositely disposed slots to receive the ends of said strips and secured together with endsvin staggered radial alignment, and means for detachably securing together the extending ends and clamping said ring snugly around said handle, a second sectional ring intermediate the, ends of said strips and also comprising fiat insulating semicircular members having oppositely extending slots to receive the strips and secured together with ends in staggered radial alignment, and means for detachably securing togethe'rthe extending ends of the ring. 7

6. In a lamp guard having radially disposed insulating strips, a sectional supportng ring for said strips, each section comprising arcuate members secured together in staggered radial, alignment, the members having oppositely disposed radially aligned slots, said strips being interlocked in said slots, and means for securing of said sections together.

In witness whereof, I have hereunto subscribed my name.
